MySQL 8 GA

New IBM Cloud® Databases for MySQL deployments

For new IBM Cloud Databases deployments, take a backup of your existing v5.7/8 database instances and import them into version 8. Use mysqldump or mydumper to import to IBM Cloud Databases. For more information, see Migrating to Databases for MySQL.

Existing IBM Cloud® Databases for MySQL v5.7 deployments

At present, in-place upgrades from MySQL v5.7 are not supported. IBM Cloud Databases is creating additional documentation to provide necessary guidance on a migration path. Until this documentation is released, upgrade existing IBM Cloud® Databases for MySQL v5.7 deployments using the following steps:

1. Create and export a v5.7x backup.
2. Migrate and prepare your backup locally to be compatible with 8.0.
3. Import into ICD MySQL 8.0.

As a best practice, retain your current v5.7 backups until the version 8 import is evaluated. Use mysqldump or mydumper to export your 5.7.x databases. For more information, see Migrating to Databases for MySQL.

Once your upgrade is complete, changes cannot be reverted. The changes are incompatible, and you cannot use the data directory from MySQL 8.0 on MySQL 5.7. Retain your MySQL v5.7 backup, as it helps to restore it on a MySQL 5.7 instance should the changes need to be reversed.
